Each arm is bowed suciently for clearance of any protuberances on the peripheral walls of the object being traced and also to permit a clear View of the object while the tool is being used. 10 AThe outer ends ofthe two arms are alike and adescription of one will `suiticefor both. Referring' to the larrn I2, which preferably is of strip material, its outer-end is bent downward relatively tothe plane Vof the arm itself as at Ill Y15 and then directed inward forming a downwardly and inwardly directed end sectionIS.l The tip of thisv section may be .rolled upon itself to form acylindrical holder iSjthroughwhich a pencil Il gagement. The axis of the pencil holder I6 is oblique tothe plane of the arms of the scriber and, in ordinary use, to the plane of the paper I8 on which the outline-,iste` be tracedisee 25 `Where there is no provision for adjusting the "Obliquity of the'A pencils the,- angle of the pencil holders .I6 is set at ab0utfi5 tothe plane of the scriber arms (seeFig. l'g) and this angle has been found to vbe right for-setting the pencil lpointsyo under the overhang above the tread of the sides -of the human foot in tracing an accurate outline of its tread, an operation incident toA correct shoe `fitting according to a newly developed system for 4 which the scriber has been especially designed. nations of parts hereinafter described and then t may be desirable` toy set `vthe pencils at otherl angles. Accordingly, as shown in Figs. 2 and 3, the pencil holderl I9 is formed of a separable piece vthe fiat tip of an inclined end section 22'. on the lscriber. arm formed as hereinbefore described. An indicator and scale,- see 23, Fig. 3, may be pro,- yvidedffor adjustment ofthe angularity of the pencils to the same or to different angles as mayl vv-The tvvo armsf I 0 and I2 are normally drawn suice to apprise those skilled in the art of `its other uses. The foot, either bare or stocknged, is placed on a sheet of` paper, thin cardboard, or

i thelike with the weight of the body thereon and,

j for accuracy, with a form of support beneathk the paper, as indicated in Fig. 1, that compensates for the shoe heel so that the body weight will spread the foot just as it does against the insole of a shoe on the foot. The scriber is opened and initially set with the two pencils kl'l at each side' of the heel and about opposite the point beneath the heel that would be determined by the rear end of an insole when the foot is in ay shoe (seeI` Then, by drawing the scriber forward. (see Fig. l) the spring 2A causes the pencils to Fig. 3).

open and close relatively to each other as they trace the curves from heel to toe of the foot. Be-

cause of the inward angle at. which 'the' pencils are set, they simultaneously enter beneath the` undercut shape of the sides of the foot vand trace the two sides of the true tread of the foot 'or substantially the true outline of the insole that should be used for tting that particular foot. When the forward movement causes the pencils to reach the toe the spring draws them together to complete the outline desired to be 'portrayed on the paper. Without the true or accurate out-` line of the tread, such as may be produced with the scriber of thisinvention, only afless accurate fitting of shoes may be had with an accompanying loss of comfort to the wearer of the shoes.,

While thefeaturesof the invention have been shown and described inY their preferred embodiment, it will be-understood that the invention may be embodied otherwise than vas shown in the drawing and described'in vthe specification and yet be within the scope oi the following claims.

What is claimedasnew, is: 1. Al scriber comprising an oppositelydisposed pair of outwardly bowed arms formed of strip' material, pivoted together at one end with their faces in substantially the same plane, each of `said strips being-bent downwardly and then inwardly at its free end and nally twisted to set their faces substantially perpendicularv to the general plane-of said two arms, a holder at each twisted end adapted to receive a marking'. pencil,

said holders beingset at diverging angles such that marking pencils carried thereby are directed downwardly and inwardly relatively to each other.

2. A scriber according to claim 1 having a contractile spring connecting said two arms between the pivot and pencil holders.

3. A scriber according to claim 1 having a contractile spring connecting said two arms be` tween the pivot and pencil holders land means for preventing contact of pencils in said holders under the arm closing inuence of said spring. 4. A scriber having two opposed arms lying in substantially the same plane, so connected to each other at one end that either may move y independently of the other in said plane, and

a marking pencil holder at the free end of` each arm, said holders being so constructed and `ar. i

said two arms. A u 5. A scriber according to claim"`4 `having the marking pencil holders each adjustably mountedr on its supporting arm to vary the said Obliquity of `the pencils carried. thereby.
